Kim Kardashian and Kanye West are having yoga lessons to ''make their love life even better''.

New mum Kim - who has already shed her baby weight since giving birth to first daughter, North, in June by adhering to a strict diet - has called in a private instructor to show her and her fiancé how to do yoga in a Hatha style in order to make them more flexible.

A source explained: ''Kim says if their bodies are more flexible, it will make their love life even better. She has convinced him that it's good for his state of mind and if he finds inner peace, he will be even more creative.''

The new exercise is said to be a big hit with the rapper, as he is very interested in connecting more with his spiritual side and opening his mind.

The source added to US OK! magazine: ''Kanye likes to see himself as spiritual and a great thinker, and suddenly he's getting all enthusiastic about Buddhism and finding his karma.''
